Hii Frnds, Today we gonna see about the SOC(System on Chip) used in our smartphones,
Are u feel interested in see about it, take a move down,,
The most common SoC used in our Smartphones are Snapdragon, Kirin, Mediatech and Exynos (used in Samsung).
The one which said to be a best SoC should have a good core count and a well performing GPU (Graphics Processing Unit) and a well fabricating technology.
lets define them in a list,
SoC (System on Chip) :
A single chip, which includes lots of different functions, is known as a SoC or a System-on-a-Chip. The chips which power our smartphones are no longer just CPUs, but a CPU plus a GPU plus a memory controller plus a DSP plus a radio for GSM, 3G and 4G LTE comms.Traditionally, the “brains” of a computer were found in the CPU (Central Processing Unit), and other necessary peripherals were found in auxiliary chips which were dotted around the CPU. These auxiliary chips included things like the GPU (Graphics Processing Unit), the memory controllers, and any specialized video or audio chips.
GPU (Graphics Processing Unit) :
There are three major designers of mobile GPUs: ARM, Qualcomm and Imagination. ARM’s range of GPUs are known as Mali and includes the Mali-T760, as found in the Exynos 7420, and the Mali T628, as found in the Kirin 935. Qualcomm’s GPUs are branded under the Adreno name with the Snapdragon 810 using an Adreno 430 and the Snapdragon 801 using a Adreno 330. The third player in the GPU space is Imagination with its PowerVR range. Imagination has had the most success on mobile with Apple, as every iPhone since the 3GS has used a PowerVR GPU. However, Imagination has also had some success on Android, and the MediaTek Helio X10 uses the PowerVR G6200.
It is difficult to make a comparison between these GPUs just from the specifications. They all support OpenGL ES 3.1, they all support RenderScript, and they all boast high gigaFLOP numbers. The real test comes when running actual 3D games.
CORE COUNT :
we can see that every major SoC uses 8 CPU cores. To support 8 CPU cores, these chips use a technology from ARM (Multi core Processor) called big.LITTLE. The idea behind big.LITTLE is that not all the cores are equal. You generally find a cluster of Cortex-A57 cores and a cluster of Cortex-A53 cores. The A57 is a high performance core, while the A53 has greater energy efficiency.
When tasks are run on the LITTLE cores they use less power, they drain the battery less, however they may run a little slower. When tasks are run on the big cores, they finish sooner but they use more battery to do so.
The improvement in performance gained by the use of a multi-core processor depends very much on the software algorithms used and their implementation. In particular, possible gains are limited by the fraction of the software that can run in parallel simultaneously on multiple cores; this effect is described by Amdahl’s law.
FABRICATING TECHNOLOGY :
The fabrication of “silicon chips” isn’t easy. In fact it is a highly complex process that involves a lot of expensive machinery. To make a chip from silicon wafer to chips ready to sell, it takes several weeks. One of the parameters of fabrication system is known as the “process node” and it defines how small the transistors are and how small the gaps are between transistors.
In semiconductor device fabrication, the various processing steps fall into four general categories: deposition, removal, patterning, and modification of electrical properties.
Modern chips have up to eleven metal levels produced in over 300 sequenced processing steps.
LETS NOW SEE ABOUT THE SoC TYPES :
Friends. As you know that Every Computer has a processor, which is responsible for it’s task. Just Like computer, Mobile Devices also have their own processors for their routine and specific tasks. Qualcomm is a leading company which is providing Snapdragon processor for mobile devices. Today we will discuss about Mobile processor “Snapdragon” or “Qualcomm Snapdragon”.
Qualcomm is 11 years old company which is working on Smartphone processors, Tablets, Wireless modems etc. Company’s super product is Snapdragon Mobile Processor. So Collectively It is called Qualcomm Snapdragon processor. Snapdragon is a suite of Soc(System on a chip).
The Snapdragon central processing unit (CPU) uses the ARM RISC instruction set. A single SoC may include multiple CPU cores(dual Core, Quad Core, Octa Core, Hexa Core), a graphics processing unit (GPU), a wireless modem, and other software and hardware to support a smartphone’s global positioning system (GPS), camera, gesture recognition and video.
Snapdragon processor are embedded in devices of various systems, including Android and Windows Phone devices. They are also used for netbooks, in cars, wearable devices and other devices. In addition to the processors, the Snapdragon line includes modems, wi-fi chips and mobile charging products.
Snapdragon Processors are divided in 5 tiers.
- 800 tier (Most premium Mobile Processors Series)
- 700 tier
- 600 tier
- 400 tier
- 200 tier
Latest Smartphone processor from Qualcomm is “snapdragon 850″
Taiwan-based MediaTek takes a lot of flak for updates, but the company’s mobile chips are in scores of phones around the world. Figuring out the naming conventions and capabilities of these MediaTek processors though can be a little daunting, though.
Don’t fret! We’ve got a guide to recent MediaTek chips, detailing features, prominent phones, and much more.
MediaTek’s Helio family is generally its most prominent chipset range, ranging from the brand-new low-end Helio A series to the now-dormant Helio X-range of flagship chips. The most prominent sub-set of chips is the MediaTek Helio P-series, which occupies the lower mid-range to upper mid-range price brackets.
MediaTek’s most powerful processor thus far was recently announced at the MWC 2018. The Helio P60 is a continuation in the Helio series most recent of which are the Helio P30, Helio P25, and Helio P23. The MediaTek Helio P60 brings out the big guns in the form of Integrated AI processing unit (APU) which allows for a faster and more accurate face detection, better image quality and augmented reality.
Samsung doesn’t kick up much fuss when it launches a new mobile processor, but chip development is a major part of the company’s business — especially given the number of smartphones it sells every year. Samsung’s mobile processors, released under the Samsung Exynos brand, cater to handset budgets across the market, from its flagship Galaxy S phones to budget J series handsets.
Here’s what you need to know about the Samsung’s current range of SoCs.
You’ll always find two variants of each high-end Samsung smartphone, one packing a Qualcomm Snapdragon processor for the U.S. market and another equipped with the company’s latest high-end Samsung Exynos chip for the global market.
The Exynos 9810 is Samsung’s current flagship SoC. It powers the Samsung Galaxy S9 and is the company’s equivalent of the more common high-performance Qualcomm Snapdragon 845. The slightly older Exynos 8895 can be found in the Galaxy Note 8 and Galaxy S8 handsets.
Samsung is the only Android chip manufacturer still working on a fully custom in-house CPU design for its flagship products, known as Mongoose or M cores. The Exynos 9810 features the third generation of this design.
CHINESE PHONE MAKER Huawei has unveiled the Kirin 970 SoC, its first homegrown mobile processor to pack a dedicated Neural Processing Unit (NPU).
The flagship processor, which has been designed by Huawei’s HiSilicon chip design business and manufactured by TSMC, will pave the way for the “future of smartphones”, according to the firm.
The Kirin 970 allows for native AI processing to be combined with cloud-based AI, while the NPU will help Huawei devices to become more intelligent and provide a more personalised experience.
This SoC will also likely power Huawei’s long-rumuored virtual AI assistant, but the firm has yet to comment. Instead, the firm demonstrated the NPU’s super speedy image recognition, which sees the Kirin 970 process 2,000 images per minute, faster than other mobile processors on the market.
On the specs front, the Kirin 970 is powered by an 8-core CPU and 12-core GPU, produced with a new 10nm process, and features 5.5 billion transistors packed into it. Huawei claims the chip has “25 times the performance with 50 times greater efficiency” than a quad-core Cortex-A73 processor, which means faster processing and less battery usage.
Huawei’s Kirin 970 CPU is expected to make its debut inside the firm’s Mate 10 and Mate 10 Pro smartphones, which are arrived.
